ALEXANDER E. HUGHES, OF ALBANY, INDIANA, ASSIGNOR TO THE GREAT AMERICANFIRE-EXTINGUISHER OOMPANY, OF LOUISVILLE, KY.

IMPROVEMENT IN CHEMICAL FIRE-EXTINGUISHERS.

Specification forming part of LetteIsPatent No. 164,837, dated June 22,1875; application filed February 10, 1875.

To all whom it may concern Be it known that I, ALEXANDER E. HUGHES, ofthe city of New Albany, in the county of Floyd and State of Indiana,have'invented certain new and useful Improvements in thereof; and Fig. 2is a rear View, showing the tank in vertical cross-section.

The truck is composed of two side bars, a a, united at the front, andextended into a neck or reach, b, at whose forward end a socket is made,to receive the tang of a clevis, c. d is the tongue, rigidly attached tothe clevis. The rear ends of bars a a are secured by a cross-piece. g isa charge-box, secured to a frame, f, attached to the bars a and neck b.h is a lantern; t, a reel, secured, adju'stably if desired, to the rearof the frame or truck. k 70 are the main wheels, secured on an axle, r,and l is a guidewheel, hung in the clevis c. e is a step, forconvenience in getting at the charge-box, or other part of theapparatus. A is a water tank or cylinder, made of sheet or other metal,hung on the axle 1", between the bars a a, so as to freely turn orrotate on said axle when required. This tank is made double by insertingthe two bottoms m and n therein, whereby a central space is left,through which the axle passes. Each half of the tank is provided with anopening, 0 p, for the reception of the acid-vessel; and this latter maybe of any proper form--such as those for which patents have heretoforebeen granted to me.- The axle r maypass entirely through the tank,

as shown, or the wheels may simply be secured to spindles, which can beattached to the outside of the tank by rivets passed through flanges onsaid spindles inner ends. The tank is retained in its vertical positionby a springloop, 2, attached to a rod, 8, of frame f, and a similarloop, a, is employed for holding the tank in a horizontal position, asindicated in Fig. 1. The two loops may be made of one piece or unitedpieces of metal.

The operation of this double tank is as follows: The two compartments orchambers being properly charged, one may be put in use, and whenexhausted, by releasing the spring 2., the other end of the tank isbrought up till the tank is in a horizontal position, where it isretained by loop at. In this position the emptied chamber may berecharged without causing any cessation of the use of the other, so thata constant stream may be had from the extinguishers.

What I claim is p 1. In a chemical fire-extinguisher, the rotating tankor cylinder, made with two chambers, adapted to be successively chargedand discharged without interfering with either operation in the other,substantially as de scribed.

2. In a mounted {chemical fire-extinguisher, a double rotating tank, A,in combination with the frame and axle of the main wheels, substantiallyas and for the purpose described.

3. In a chemical fire-extinguisher, the double rotating tank A, incombination with the retaining-loops t a, substantially as shown anddescribed.

4. A mounted chemical fire-extinguisher, composed of the truck, rotatingtank, and charge-box, constructed and arranged substantially as shownand described.
